DuraVent DuraChimney II 8 to 16 inch Firestop Spacer: closes the openings between floors around your chimney
The DuraVent DuraChimney II 8 to 16 inch Firestop Spacer is a square plate with a collar around the chimney opening. It closes the space around the pipe so fire cannot spread between floors through that opening. Building codes require one at every floor and ceiling crossing, including the attic entrance, but not at the roof. It attaches beneath the framing with a nail or screw at each corner. DuraChimney II is DuraVent’s air cooled chimney, a double wall pipe in 8 to 16 inch sizes for fireplaces that burn wood, oil, coal, or gas.
Air between the stainless steel inner wall and galvanized steel outer wall keeps the outside cool and the inside hot for draft. The pipe can expand with heat without causing damage. Choose an 8, 10, 12, 14, or 16 inch spacer to match your chimney diameter. DuraChimney II parts are made to order and cannot be returned. Continuing into the attic? Add the DuraVent DuraChimney II 8 to 16 inch Attic Insulation Shield, the guard above this spacer. The DuraVent DuraChimney II 8 to 16 inch Firestop Spacer ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
